Rapid-sequence induction of anaesthesia is a challenging situation for the anaesthetist. The major considerations are rapid protection of the airway by a cuffed cndo-CAN J ANAESTH 1995 / 42:10 / pp 875-8

P Pu ur rp po os se e: : Corrective strabismus surgery is associated with moderate pain after surgery. Postoperative analgesia for these patients may include topical local anesthetic agents and topical non-steroidal antiinflammatory drugs. In this prospective randomized, double-blind placebo controlled clinical trial we compared the effect of placebo to intraoperative 0.5% topical amethocaine or 0.5% topical ketorolac on pain control after strabismus surgery in children.

P Pu ur rp po os se e: : To investigate if 50% nitrous oxide reduces the pain during injection of propofol mixed with lidocaine in children.M Me et th ho od ds s: : Healthy children undergoing iv induction of general anesthesia for elective surgery were recruited into this prospective, randomized, double-blind study. None of the patients received any premedication except for eutectic mixture of local anesthetics cream. Before induction of anesthesia with propofol 1% mixed with lidocaine 0.05% (propofol dose 3 mg·kg -1 ), the treatment group received 50% N 2 O in O 2 and the control group received 100% oxygen. Pain due to propofol administration was rated with a four-point behavioural scale: none, mild, moderate or severe.R Re es su ul lt ts s: : There were 28 subjects in the control group and 26 subjects in the treatment group. Demographic data were similar in both groups. The incidence of pain at induction was 4% after N 2 O and 36% in the control group, P < 0.01. No patients had severe pain. Most patients had mild pain. Three of the ten patients with pain in the control group had moderate pain. The number needed to treat was 3:1.C Co on nc cl lu us si io on n: : Nitrous oxide reduces pain during induction with propofol mixed with lidocaine in healthy children. ROPOFOL has many beneficial pharmacodynamic and pharmacokinetic properties. However, one of its major adverse effects is injection pain. Incidence of propofol injection pain in children varies between 28% and 85%. 1 Lidocaine is commonly mixed with propofol to reduce pain of propofol administration. This, however, does not completely remove the pain in all cases. We hypothesized that 50% N 2 O in O 2 would further reduce the pain of propofol administration in children. Objectif

Hypospadias is a common anomaly among males 1 with several variations, each with a slightly different surgical approach toward correction of the defects in the urethral fold and ventral foreskin. 1 Previous studies have demonstrated that duration of surgery and type of hypospadias repair impact surgical results. Additional complicating factors were the specific surgical technique, patient age, penile engorgement, postoperative inflammatory response, and tissue edema. [1][2][3][4][5][6][7][8] Recent publications from centers in the United States, India, and Korea report that children undergoing hypospadias repair with caudal regional anesthesia/analgesia could have increased postoperative surgical complications. [2][3][4][5] This was unexpected to many of us, AbstractBackground: Recent publications from the United States, India, and Korea report that children undergoing hypospadias repair with caudal regional anesthesia/analgesia could have increased postoperative surgical complications. Aims:The purpose of this retrospective cohort study was to assess the impact between caudal regional anesthesia, other regional anesthesia, and no regional anesthesia on complications after hypospadias repair at a tertiary care children's hospital in Ottawa, Canada, with an expectation to changing practices if a link was found. Method:We reviewed the health records of 827 children with hypospadias undergoing penile surgery from January 1991-June 2017. The final sample size for the analysis consisted of 764 patients and 825 procedures. Results:The overall complications were almost identical when considering anesthesia effects, and this similarity persisted when we assessed specifically for only surgical complications. We had 716, 94, and 15 subjects who had a caudal block, penile block, and general anesthesia only, respectively, and their complication rates were 28, 31, and 27%, respectively, and their fistula formation rates were 10, 6, and 0%, respectively, and their stricture formation rates were 8, 7, and 20%,, respectively.Hypospadias type and surgical repair technique were marked predictors of complications in the postoperative period.Conclusion: Anesthesia technique appears to have minor impact on complications after hypospadias repair, while surgical technique and type of hypospadias impact complications after hypospadias surgery in children. Based upon these results, we will not change our current practice of using a variety of regional anesthesia techniques for children undergoing hypospadias repair. K E Y W O R D Sanesthesia, caudal, complications, hypospadias repair, regional anesthesia | 761as a caudal has been routine practice of pediatric anesthesiologists for 40+ years and is strongly supported by most surgical colleagues and families.We wanted to review our results and determine if the issues and concerns noted in other centers were also occurring at Children's Hospital of Eastern Ontario, Ottawa, Canada. If so, we would need to change our routine practice to an improved, evidence-based medicine practice, ie, stop ...
